* The =openpam_nullconv function is a null conversation function suitable
* for applications that want to use PAM but don't support interactive
* dialog with the user. Such applications should set =PAM_AUTHTOK to
* whatever authentication token they've obtained on their own before
* calling =pam_authenticate and / or =pam_chauthtok, and their PAM
* configuration should specify the ;use_first_pass option for all modules
* that require access to the authentication token, to make sure they use
* =PAM_AUTHTOK rather than try to query the user.
